Assim, objetivou-se investigar a presença de coliformes totais e fecais em amostras de água provenientes de poços e lago no Bairro Recreio Jardim Mina de Botucatu, São Paulo, e na margem e meio do canal do Rio Tietê, Represa da Barra Bonita, próxima da Usina da Barra Bonita, Botucatu, São Paulo. A necessidade de investigação ocorreu em virtude do alto índice de gastrenterites detectado na população que utilizam esses recursos hídricos. Foi analisado o Número Mais Provável (NMP) de Coliformes Totais e Fecais em 168 amostras de água através do método de tubos múltiplos. De acordo com resultados, verificou-se que, somente 42% das amostras coletadas nos 4 poços investigados, foram consideradas de boa qualidade para o consumo humano, considerando este parâmetro, por não apresentarem coliformes fecais em 100 mL de água, segundo a Portaria MS 518 de 25/103/2004. Quanto aos Padrões de Balneabilidade, segundo a Resolução 357 do CONAMA de 17/03/2005, pode-se observar que nos locais investigados, somente 10% das amostras analisadas foram consideradas impróprias para banho e as 90% restantes foram consideradas satisfatórias. Water, fundamental to the existence of mankind, demands the attention of competent authorities since its contamination could become a vehicle for transmission of infectious diseases. Thus the present work aimed to investigate the presence of fecal and total coliforms in water samples taken from wells, a lake and both the margin and channel of the Tiete River, Barra Bonita Dam, Botucatu, São Paulo, Brazil. The necessity of investigation arose by virtue of a high gastrenteritis index detected in the population that utilizes these hydric resources. The most probable number (MPN) of fecal and total coliforms was determined for 168 water samples through the method of multiple tubes. The results showed that only 42% of the samples collected in 4 wells investigated were considered of good quality for human consumption, by not presenting fecal coliforms in 100 mL of water, according to Decree Nº 518 de 25/103/2004. Regarding suitability for bathing/recreational use, according to CONAMA Resolution 357 of 17/03/2005, it was observed that in the locations investigated, only 10% of the samples analyzed were considered inappropriate for bathing and 90% of the remainder were considered satisfactory.

A expansão da família zoológica no médio e alto rio Paraná iniciou-se após o represamento do Salto de Sete Quedas, atingindo a foz dos rios Paranapanema e Tietê, com invasão de um amplo trecho do baixo rio Tietê. Foram mapeadas dezesseis arraias do gênero Potamotrygon, por meio do monitoramento do produto pesqueiro dos pescadores, entre os municípios de Pereira Barreto e Buritama, Estado de São Paulo. As arraias aproveitam-se das eclusas das Usinas Hidrelétricas, avançando rapidamente. Não são animais agressivos, contudo, se pisoteadas ou manipuladas, chicoteiam a cauda contra o agressor. A arraia possui de 1 a 4 ferrões recobertos por um epitélio produtor de peçonha e podem causar importantes envenenamentos em pescadores e banhistas. O avanço destes peixes peçonhentos em áreas onde não existiam requer programas de esclarecimentos e interação com a comunidade para evitar acidentes graves em banhistas e pescadores e extermínio sem razão dos animais. The freshwater stingrays are fish adapted to waters of the rivers and lakes, only existing in the hydrographic basins of South America. The expansion of the zoological family in the middle and upper Paraná River started after the damming of the Salto de Sete Quedas, reaching the mouth of the Paranapanema and Tietê Rivers and colonizing upstream in the stretch of the lower Tietê River. Sixteen freshwater stingrays of the genus Potamotrygon were mapped, by monitoring the fishery product of fishermen, between the municipalities of Pereira Barreto and Buritama, State of São Paulo. The stingrays take advantage of the locks of the Hydroelectric Plants, advancing rapidly. They are not aggressive animals, however, if trampled or manipulated, they whip the tail that has 1 to 4 stingers covered by a venom-producing epithelium and can cause important injuries to fishermen and bathers. The advancement of these venomous fish in areas where they did not exist requires programs for clarification and interaction with the community, to avoid serious accidents with envenomations in bathers and fishermen and the unreasonable extermination of animals.

Myxospores were found in the gill tissue of P. lineatus with a prevalence of 10%. The myxospores consisted of two elongate, elliptical shell valves each with a long, tapering caudal appendage. The morphology was consistent with Henneguya and the myxospore measured as follows (mean ± SD): total length 55.5 ± 2.1 μm, body length 16.2 ± 1.1 μm, body width 5.5 ± 0.1 μm, caudal appendages length 39.0 ± 2.0 μm. The polar capsules were 7.3 ± 0.2 μm long, 1.7 ± 0.2 μm wide and contained a polar filament coiled 11 to 13 turns. Histological analysis showed the plasmodia developing in the middle region of each gill filament and caused a focally extensive distension by forming a space-occupying mass within the gill filament. The ultrastructural analysis allowed the observation of the presence of mature myxospores throughout the plasmodium. Phylogenetic analysis with the SSU rDNA gene showed Henneguya tietensis n. sp. as a sister species of the subclade formed by Henneguya piaractus and Henneguya brachypomus that infect fishes of the genus Piaractus. The genetically closest species was H. piaractus, which showed a similarity of 82.4%. Using molecular and morphological characterization, the myxozoan parasite described herein represents a new species of the genus Henneguya.

Although EROD activity has been widely used as a biomarker of exposure to polycyclic aromatic hydrocarbons in fish, this activity can be influenced in the field by spatial-, seasonal- or individual-related factors. We therefore performed a comparative study of hepatic EROD activity levels in the croaker Plagioscion squamosissimus to determine whether variations existed in enzyme activity levels, especially in relationship to reproductive status, fish size, age, and seasonality. For this purpose, we collected fish from three reservoirs with different pollution levels during the early-rainy (November 2012), rainy (March 2013), and dry (July-August 2013) seasons from the Tietê River, Brazil. We tested whether size, age and sex affected EROD activity among the localities and seasons. We found a marked effect of pollution during the dry season on variation among the localities in EROD activity in P. squamosissimus. An analysis of covariance indicated that sex had a significant negative effect on the seasonal variability of the EROD activity levels at the most polluted locality (near São Paulo). A possible explanation for the statistical association between EROD activity and sex is that the reproductive status of the females influenced the EROD activity levels. A possible explanation for the statistical association between EROD activity and sex is that the reproductive status of the females influenced the EROD activity levels, also largely reported in the literature. Our results suggest that reproductive status can be a significant confounding factor for determining EROD activity in female P. squamosissimus in freshwater ecosystems when compared to males. Moreover, our results suggest that the presence of phenanthrene during the dry season at Barra Bonita reservoir might explain the highest EROD activity responses in this period of study.

AIM: The reservoirs of the medium and low Tietê River are disposed as a "cascade series", in which time, physiographic features and influence from drainage basins present differences that determine variability in their dynamics. These reservoirs are submitted to different impacts from the urban centres which they drain, and also from agricultural activities.Considering these features, the aim of this work was to characterize the Medium and Low Tietê river stretches by limnological analysis (including water and sediments) considering dry and rainy seasons evaluating changes along the reservoirs sequence. METHODS: Based on physical and chemical measurements on water and sediments from 16 points along the reservoirs and in the river mouth of the main tributaries, it was possible to make an environmental characterization of the study area. RESULTS: This was performed focusing on water, sediment, habitat structure and time scale. Generally, the data showed a reduction in the values of the analyzed parameters along the reservoirs sequence. Moreover, it was possible to identify differences between the dry and rainy seasons for water and sediment parameters. Concerning habitat structure, there is a gradient along the river, which shows that the environmental quality improves from the river head to the river mouth. Differences in macrophyte composition, kind of sediments, transparency and habitats were also identified. CONCLUSIONS: Therefore, modifications were identified in the habitats general structure along the medium Tietê stretch: emerging macrophytes and muddy bottom predominate upstream; and submerging macrophytes and sandy bottom predominate downstream. The water characteristics should be taken into consideration, because they reflect the impacts upon the drainage basin of each reservoir.

Esse artigo trata do processo de retificação do rio Tietê, em São Paulo cujo estudo foi iniciado no fim do século XIX e busca detectar as principais implicações geradas por essa intervenção. Procura-se compreender como a retificação do Tietê atuou como parte de um processo de urbanização acelerada onde os interesses imobiliários reforçaram os interesses da indústria automobilística recém implantada, o que veio a justificar a construção de avenidas marginais ao longo do rio retificado. São discutidos equívocos ocorridos e consequências desse processo no que diz respeito à ocupação do solo e a destruição da natureza, acarretando problemas urbanos e ambientais até os dias de hoje. This paper deals with the straightening process of the Tiete River in Sao Paulo, Brazil, which began by the end of the nineteenth century. It aims to detect the implications generated by this intervention. This study also brings up the relation of the straightening of Sao Paulo’s rivers and the implementation of the automobile industry and the investments in a road plan to justify the construction of expressways on the banks of the Tiete River. It also speculates about the use of cars and the environment decay in the city due to the use of this type of transportation system. The article discusses mistakes that occurred in consequence of this process, concerning land occupation and the destruction of nature, which implies in urban and environmental problems to these days.

Son discutidos equívocos ocurridos y consecuencias de ese proceso no que dice respecto a la ocupación del suelo y a la destrucción de la naturaleza, acarreando problemas urbanos y ambientales hasta los días de hoy.

RESUMO Um modelo de simulação de OD e DBO, combinando rios e reservatórios, foi desenvolvido no aplicativo Microsoft Office Excel e aplicado no rio Tietê, trecho entre Pirapora do Bom Jesus e Salto, conhecido por ser poluído devido ao recebimento do aporte de carga orgânica remanescente da Região Metropolitana de São Paulo. Na calibração utilizaram-se dados monitorados e ferramentas de otimização. Foram simulados 12 cenários caracterizados pela combinação das seguintes variáveis: vazão descarregada (700, 411 e 130 m3/s), nível do reservatório (691 e 688 m) e concentração de DBO afluente ao reservatório de Pirapora (37 e 56 mgO2/L). A análise destes cenários permitiu avaliar os possíveis impactos da operação do reservatório na qualidade da água do rio Tietê a jusante deste barramento. Os resultados indicaram que a qualidade da água afluente ao reservatório sobressai perante os aspectos operacionais do mesmo. Diminuir o aporte dessa carga orgânica remete a um planejamento de longo prazo. Uma alternativa de curto prazo para minimizar os impactos é operar o reservatório com descarga baixa (130 m3/s), mantendo o nível normal (691 m). Desta maneira, quando a concentração de DBO afluente é alta (56 mgO2/L), o trecho entre Pirapora do Bom Jesus e Cabreúva fica anóxico e a região de Salto apresenta concentrações de OD e DBO de 3 e 20 mgO2/L, respectivamente. Quando é normal (37mg/L), não é encontrada condições de anaerobiose em todo o trecho simulado e a região de Salto apresenta concentrações de 6 mgO2/L e DBO igual a 17 mgO2/L. ABSTRACT A simulation model of DO and BOD combining rivers and reservoirs, was developed in the software Microsoft Office Excel and used in the Tietê river, stretch between Pirapora do Bom Jesus and Salto, known to be polluted due to the receipt of the remaining organic load contribution to Metropolitan Region of São Paulo. The calibration used to monitored data and optimization tools. They were simulated 12 scenarios characterized by the combination of the variables: discharged flow (700, 411 and 130 m3/s), level of the reservoir (691 and 688 m), and input concentration of BOD to Pirapora reservoir (37 and 56 mgO2/L). With these analysis of the scenarios was possible to evaluate the impacts of reservoir operation on the water quality of the Tietê River downstream of this dam. The results indicated that the water quality to input on reservoir protrudes towards the operational aspects. Reduce the contribution that organic load refers to a long-term planning. A short-term alternative is to minimize the impacts operate with low discharge reservoir (130 m3/s), while keeping the normal level (691 m). Thus, when the input concentration of BOD is high (56 mgO2/L), the stretch between Pirapora do Bom Jesus and Cabreúva is anoxic and the region of Salto presents DO and BOD concentrations of 3 and 20 mgO2/L, respectively. When normal (37 mgO2/L), is not found anaerobic conditions throughout the simulated stretch and the region of Salto presents concentrations of 6 mgO2/L and BOD equal to 17 mgO2/L.

From educational design perspective, our goal is to identify the potential of this means of visual communication in order to discuss the environmental routine of Tiete River, in the state of S??o Paulo, which is highly polluted and contaminated nowadays. The objective is to recognize the problems, needs and expectations regarding the use of the photography applied in the design of the Communication and Language discipline mentioned above at the Pedagogy course. The collected data will provide basis and consolidate the intervention project, with one Public State Elementary School/Secondary Education, Youth and Adult Education - Supplementary, located in the East Zone of S??o Paulo city. The possibility is that the dynamic digital photography has dialogic potential. However, it is rarely used to discuss daily situations in distance learning. The theoretical framework of the educational field which supports the study derives from Paulo Freire's work (2014, 2014th, 2011, 2011a, 2010) and his followers: Gadotti Moacir (2010) and Paulo Padilha (2002). Similarly, the theoretical framework of the field of communication is provided by Pierre L??vy (2004, 2011, 2011a, 2014) and researchers who gave it continuity: Andrea Filatro (2008); Francisca Severino (2001); Jo??o Mattar (2014) and Margarita Gomez (2004). The methodological procedures of a qualitative approach are the documentary analysis, conversation circle and content analysis, based on Eloiza Szymanski (2004). The research results contributed to the use of digital photography as an educational tool in the educational design, thus being able, under certain conditions, to have their use in the Pedagogy course of distance learning. . The research was developed at Basic School research group , Management and Intervention, under the coordination of Professor Dr. Eleodora Francisca Santos Severino, at the Post - Graduate Program in Management and Educational Practices at UNINOVE which was recommended by CNPQ A pesquisa tem por objeto a fotografia digital no design educacional do curso de Pedagogia de um Centro Universit??rio.

The present piece aims to discuss the new relations between waterfronts and the contemporary city. Particularly, about intervention projects in areas along riversides, or river banks, that were embraced by the urban environment. This study demonstrates the importance of water resources, and their interactions with the landscape, society and urban environment, becoming part of the current debate about sustainable urban development. Therefore, the focus here is on Tietê river, on its urban stretch inside the city of São Paulo, and the urban intervention master plan, proposed during Fernando Haddad's tenure as mayor (2013-2016), for the area alongside the river, named "Arco Tietê". The intention of this paper is to investigate the bounds, the possibilities and challenges related to the reintegration of Tietê river into the landscape and urban tissue of São Paulo. It understands that all the plans and projects in the region must prioritize the area`s environmental recovery and should attempt to assimilate the river into the urban environment, not simply eliminating risks and local vulnerabilities, but also contributing systemically to the social and environmental improvement of the metropolitan area. To develop this work, a conceptual matrix is establishes that intends to direct the conception and observation of urban projects in waterfront areas. To compose this matrix, some parameters are extracted from theoretical concepts, as well as from three reference projects of urban intervention adjacent to rivers, namely: "Los Angeles River Revitalization Master Plan" LARRMP, in Los Angeles USA; MRIO, Manzanares river, in Madrid - Spain; "Cheonggyecheon Restoration Project", in Seoul Korea Republic. The role of Tietê river inside the metropolis constitution is described and contextualized, discussing local problems and possibilities. The Strategic Master Plan of São Paulo`s city (Plano Diretor Estratégico - PDE)‟s proposal for the river is verified demonstrating how Arco Tietê" is being implemented. It also shows some of the proposals in the pre-feasibility scope study which are emphasized from an environmental perspective. The piece concludes that in spite of it being the area‟s primordial element, the river is not a priority in the development of "Arco Tietê". Esta pesquisa discute as novas relações entre as frentes d‟água e a cidade contemporânea. Especificamente, sobre projetos de intervenção em áreas localizadas junto às margens de rios, ou bordas fluviais que foram englobadas pelo meio urbano. Desse modo, relaciona-se à importância dos recursos hídricos, suas interações com a paisagem, sociedade e meio urbano. Insere-se no debate atual sobre desenvolvimento urbano sustentável. Apresenta como foco o rio Tietê, em seu trecho urbano dentro do município de São Paulo e o plano-projeto de intervenção urbana, proposto na gestão do prefeito Fernando Haddad (2013-2016) para a área ao longo do rio, o Arco Tietê . Tem como objetivo investigar os limites, as possibilidades e os desafios relacionados à reintegração do Tietê à paisagem e ao tecido urbano da cidade de São Paulo. Entende que os planos e projetos para a região devem ter como prioridade a recuperação ambiental da área. Devem procurar integrar o rio ao meio urbano, não só eliminando os riscos e as vulnerabilidades locais, mas ainda contribuindo de forma sistêmica para a melhora socioambiental de toda a metrópole. Para o desenvolvimento do trabalho, se estabelece uma matriz conceitual, que pretende direcionar a concepção e observação de projetos urbanos em bordas fluviais.

An evaluation was made of the quality of samples of water and sediment collected from a series of reservoirs in the Tietê River (SP), based on limnological and ecotoxicological analyses. The samples were collected during two periods (Feb and Jul 2000) from 15 sampling stations. Acute toxicity bioassays were performed using the test organism Daphnia similis, while chronic bioassays were carried out withCeriodaphnia dubia and Danio rerio larvae. The water samples were analyzed for total nutrients, total suspended matter and total cadmium, chromium, copper and zinc concentrations, while the sediment samples were examined for organic matter, granulometry and potentially bioavailable metals (cadmium, chromium, copper and zinc). The results obtained for the limnological variable, revealed differences in the water quality, with high contribution of nutrients and metals for Tietê and Piracicaba rivers, besides the incorporation and sedimentation, consequently causing a reduction of materials in Barra Bonita reservoir, thus promoting the improvement of the water quality in the other reservoirs. The toxicity bioassays revealed acute toxicity for Daphnia similis only in the reservoirs located below Barra Bonita dam. On the other hand, chronic toxicity for Ceriodaphnia dubia and acute for Danio rerio showed a different pattern, decreasing in magnitude from Barra Bonita to Três Irmãos, demonstrating an environmental degradation gradient in the reservoirs.

Os camarões são provenientes do Rio Tietê, estado de São Paulo, Brasil, e foram coletados em um ambiente lótico abaixo da Barragem de Ibitinga. Essa população foi comparada com outras populações provenientes de ambientes continentais, incluindo a de um estudo anterior na represa da barragem de Ibitinga. Quatro amostras de 30 minutos foram realizadas mensalmente, utilizando armadilhas, de janeiro a abril de 2011. Cada indivíduo macho foi mensurado em relação a sete dimensões corporais, sendo elas: comprimento da carapaça (CL), comprimento total do quelípodo direito (RCL), comprimento do dáctilo (DCL), comprimento do própodo (PPL), comprimento do carpo (CRL), comprimento do mero (ML) e comprimento do ísquio (IL). O crescimento relativo foi analisado de acordo com as mudanças nas taxas de crescimento de determinadas partes do corpo em relação à variável independente CL. Os quatro morfotipos descritos para a espécie foram encontrados, utilizando análises morfológicas e morfométricas. Diferentes características biológicas foram encontradas entre a população estudada e as demais, incluindo a proveniente do reservatório. A população de machos da represa de Ibitinga e do Pantanal apresentaram tamanhos médios e número de morfotipos inferiores aos da população estudada aqui. Essas diferenças parecem estar intimamente relacionadas às características ecológicas dos ambientes onde estas populações estão inseridas. A hipótese de que populações costeiras e continentais de M. amazonicum pertençam à mesma espécie é suportada por nossos resultados. This study records, for the first time, the occurrence of all four male morphotypes in a population of Macrobrachium amazonicum from a continental environment, with an entirely freshwater life cycle. The specimens studied came from the Tietê River, state of São Paulo, Brazil, and were collected in a lotic environment downstream from Ibitinga Dam. This population was compared with other continental populations, including a population from the dam itself, collected in a previous study. Four samples of 30 minutes were taken monthly, using a trap, from January to April 2011. Each male specimen was measured with respect to seven body dimensions as follows: carapace length (CL), right cheliped length (RCL), dactyl length (DCL), propodus length (PPL), carpus length (CRL), merus length (ML) and ischium length (IL). The relative growth was analyzed based on the change in growth patterns of certain body parts in relation to the independent variable CL. The four male morphotypes proposed for the species were found using morphological and morphometric analyses. Different biological characteristics were found between the populations studied. The male population of the lake of Ibitinga and from Pantanal presented mean sizes and number of morphotypes lower than the population studied here. These differences seem to be closely related to ecological characteristics of the environments inhabited by these populations. Our results supported the hypothesis that coastal and continental populations of M. amazonicum belong to the same species.

AIM: The reservoirs of the medium and low Tietê River are disposed as a "cascade series", in which time, physiographic features and influence from drainage basins present differences that determine variability in their dynamics. These reservoirs are submitted to different impacts from the urban centres which they drain, and also from agricultural activities.Considering these features, the aim of this work was to characterize the Medium and Low Tietê river stretches by limnological analysis (including water and sediments) considering dry and rainy seasons evaluating changes along the reservoirs sequence. METHODS: Based on physical and chemical measurements on water and sediments from 16 points along the reservoirs and in the river mouth of the main tributaries, it was possible to make an environmental characterization of the study area. RESULTS: This was performed focusing on water, sediment, habitat structure and time scale. Generally, the data showed a reduction in the values of the analyzed parameters along the reservoirs sequence. Moreover, it was possible to identify differences between the dry and rainy seasons for water and sediment parameters. Concerning habitat structure, there is a gradient along the river, which shows that the environmental quality improves from the river head to the river mouth. Differences in macrophyte composition, kind of sediments, transparency and habitats were also identified. CONCLUSIONS: Therefore, modifications were identified in the habitats general structure along the medium Tietê stretch: emerging macrophytes and muddy bottom predominate upstream; and submerging macrophytes and sandy bottom predominate downstream. The water characteristics should be taken into consideration, because they reflect the impacts upon the drainage basin of each reservoir. OBJETIVO: Os reservatórios do médio e baixo Tietê compõem uma série em "cascata" cujas idades, características fisiográficas e influencia da bacia de drenagem apresentam diferenças determinando diferenças nas suas dinâmicas. Tais reservatórios são submetidos a diferentes impactos pelos centros urbanos as quais drenam e também pela atividade agrícola. Considerando essas características, este trabalho teve como objetivo caracterizar o médio e baixo Tietê através da análise limnológica (água e sedimento), considerando as épocas seca e chuvosa avaliando mudanças ao ao longo da sequência de reservatórios. MÉTODOS: Com base em amostragens físicas e químicas da água e sedimento em 16 pontos ao longo dos reservatórios e na foz dos principais tributários foi possível realizar uma caracterização ambiental da área de estudo focando a água, o sedimento, a estrutura de habitats e a escala temporal. RESULTADOS: Os resultados mostraram de forma geral redução dos valores dos parâmetros analisados ao longo da seqüência de reservatórios. Além disso, foi possível identificar diferenças entre as épocas seca e chuvosa tanto para os parâmetros da água como de sedimento. Com relação a estrutura de hábitats há um gradiente ao longo do rio mostrando melhora na qualidade ambiental no sentido montante-jusante e também diferenças na composição das macrófitas, tipo de sedimento, transparência e habitats. CONCLUSÕES: Foram identificadas modificações na estrutura geral dos habitats ao longo do trecho médio Tietê: macrófitas emergentes e fundo lodoso predominam a montante enquanto macrófitas submersas e fundo arenoso predominam a jusante. As características da água deve ser levado em consideração, porque eles refletem os impactos sobre a bacia de drenagem de cada reservatório.

Nile tilapia (Oreochromis niloticus), which is exotic to South America, is the most common species caught in artisanal fisheries at the Barra Bonita Reservoir, Southeastern Brazil. This species is of great socioeconomic importance for the region and keeps active a population of about 500 fishers. In the present study we assess reproduction, food dynamics and level of exploitation of O. niloticus, caught by artisanal fisheries in the Barra Bonita Reservoir. Specimens were collected monthly, from July 2004-June 2005, and a total of 1 715 specimens were analyzed. Each specimen was examined to obtain biological and biometric data: standard length (cm), total weight (g), reproductive data (sex and stage of maturation), and stomach contents (empty, partly full, and full). We also estimated the sex ratio (by macroscopic observation of gonads), reproductive period (by ovarian development and seasonal average of gonadosomatic index in females), and feeding habits (by stomach contents). The possible relationship between abiotic factors and the reproductive period was statistically verified using Spearman’s Rank Correlation. The FiSAT (ELEFAN I) package was used to assess growth parameters, mortality rates and to infer exploitation rate from standard length frequencies. The O. niloticus population had a sex ratio of 1.3:1 (M:F). Results indicated that ripe females were captured throughout the year, with a higher frequency during the winter-2004 (with a frequency of 59%, at a mean temperature of 20.5°C), and in spring-2004 (with a frequency of 60.5% at a mean temperature of 21.18°C). The GSI mean values obtained by season were: winter-2004: 1.71; spring-2004: 1.72; summer-2005: 0.80, and autumn-2005: 1.19. The Spearman correlation indicated positive values with respect to pH, dissolved oxygen, electric conductivity, transparency and chlorophyll a, and negative values with respect to temperature, accumulated rainfall and altimetric benchmark. The main food items were phytoplankton and periphytic algae, observed in 99.6% of the analyzed stomachs. The estimated growth and mortality parameters were: L∞=33.60cm, k=0.63/year, longevity= 4.76years, Z=2.81/ year, M=1.20/year and F=1.61/year. The weight-length relationship was Ln Wt=-2.8532+2.8835 Ln Lp. The estimated yield per recruit values were as follows: E=0.570, Emax=0.776, E0.1=0.604 and E0.5=0.349. These results indicate that a well established population of O. niloticus is present at Barra Bonita Reservoir; with an active reproduction throughout the year, more intense during winter and spring, and that O. niloticus is a phytoplanktophagus species. There were no indications that this species is being overfished, we therefore recommend that, due to its exotic condition, no restrictions need to be taken on its fishing activities. Rev. Biol. Trop. 60 (2): 721-734. Epub 2012 June 01.La exótica tilapia del Nilo (Oreochromis niloticus) es la especie mayormente capturada en la pesquería artesanal del embalse de Barra Bonita, sudeste de Brasil, de gran importancia socioeconómica para la región y para una población de unos 500 pescadores. El estudio analizo: la reproducción, la dinámica alimentaria y la explotación de O. niloticus, la cual fue capturada en la pesquería del embalse de Barra Bonita. Asimismo, se tomaron muestras mensuales y se analizo un total de 1 715 animales desde julio-2004 a junio-2005. De cada espécimen, se obtuvieron los siguientes datos biológicos y biométricos: longitud estándar (cm), peso total (g), datos reproductivos (sexo y estadio de maduración), contenido estomacal (vacio, parcialmente lleno y lleno). Estos datos fueron utilizados para estimar la proporción de sexo (a través de la observación macroscópica de las gónadas), el periodo reproductivo (a través de la distribución de la frecuencia de los estadios macroscópicos del desarrollo de los ovarios), y la media de la proporción del índice gonadosomático IGS de hembras, así como los hábitos alimentarios (a través de la observación del contenido estomacal). Para verificar las posibles relaciones entre los factores abióticos y el periodo reproductivo fue aplicada la correlación de Spearman. El software FiSAT (ELEFAN I) fue utilizado para evaluar los parámetros de crecimiento, tasa de mortalidad e inferir el grado de explotación, en donde se usaron los datos de frecuencia de longitud estándar. La población de O. niloticus presento una proporción de sexo 1.3:1 (M:H). Los resultados indicaron que hembras fueron muestreadas durante todo el ano, pero ha sido más frecuente en el invierno-2004-59.0% (temperatura media=20.05°C) y primavera-2004-60.5% (temperatura media=21.18°C). Los valores medios del IGS fueron: invierno-2004=1.71, primavera- 2004=1.72, verano-2005=0.80 y otoño-2005=1.19. La correlación de Spearman fue positiva para pH, oxigeno disuelto, conductividad eléctrica, transparencia y clorofila a, y negativo para temperatura, pluviosidad acumulada y variación del nivel del agua en el embalse. Los principales ítems de alimentación fueron fitoplancton y algas perifiticas observadas en 99.6% de los estómagos analizados. Los parámetros estimados del crecimiento y mortalidad fueron los siguientes: L∞=33.60cm, k=0.63/año, longevidad= 4.76 años, Z= 2.81/año, M=1.20/año y F=1.61año. La relación peso-longitud fue Ln Wt=-2.8532+2.8835 Ln Lp. Los valores de producción por reclutamiento estimado fueron=0.570, Emax=0.776, E0.1=0.604 y E0.5=0.349. Estos resultados indican que la población de O. niloticus está bien establecida en el embalse de Barra Bonita. Además, su reproducción ocurre durante todo el ano, pero es más intensa en el invierno y primavera; su dieta tiene como base el fitoplancton. Los resultados indican que no está ocurriendo sobrepesca de O. niloticus, por tanto, recomendamos que, debido a su naturaleza exótica, no se tomen restricciones a la hora de su pesca.

Populations of Synchaeta jollyae (Shiel & Koste, 1993) (Rotifera), a species recently recorded for the first time in Brazil and South America, were analyzed in reservoirs in Southeast Brazil. Sampling was carried out monthly from August 2006 to July 2007 at Furnas Reservoir in the Rio Grande basin, state of Minas Gerais, and in four cascade reservoirs in the Tietê River basin (Barra Bonita, Bariri, Ibitinga and Nova Avanhandava) state of São Paulo, in June and September 2008 and in January and May 2009. Synchaeta jollyae occurred in most samples and periods. From the results obtained it is evident that S. jollyae occurs in water bodies of varied trophic status but reaches larger populations in eutrophic water bodies and during lower temperature periods. The greatest densities of S. jollyae were found in the eutrophic Bariri Reservoir, on the Tietê River, during the winter. Mann-Whitney test confirmed the significant difference between the population densities in periods of high and low temperatures, with populations reaching higher densities at lower temperatures. It is not yet possible to tell whether S. jollyae is a widely distributed species that has been overlooked in previous plankton studies in South America. Wherever these populations of S. jollyae might have originated, it appears to be a species well established and adapted to a wide range of conditions in the Neotropics. Populações de Synchaeta jollyae (Rotifera, Synchaetidae), uma espécie recentemente registrada pela primeira vez no Brasil e América do Sul, foram analisadas em reservatórios do Sudeste do Brasil. As amostragens foram realizadas mensalmente de agosto de 2006 a julho de 2007 no Reservatório de Furnas, bacia do rio Grande, estado de Minas Gerais e em quatro reservatórios em cascata na bacia do rio Tietê (Barra Bonita, Bariri, Ibitinga e Nova Avanhandava), estado de São Paulo, em junho e setembro de 2008, e janeiro e maio de 2009. Synchaeta jollyae ocorreu na maioria das amostras e períodos. Pelos resultados obtidos é evidenciado que S. jollyae ocorre em corpos d'água com variados graus de trofia, porém atinge maiores densidades em corpos d'água eutróficos e em períodos de temperaturas mais baixas. As maiores densidades foram registradas na bacia do rio Tietê, no reservatório eutrófico de Bariri durante o inverno. O teste de Mann-Whitney evidenciou diferença estatisticamente significante entre as densidades populacionais de S. jollyae nos períodos com temperaturas mais baixas e temperaturas altas, com as populações atingindo maiores densidades em temperaturas menores. Ainda não é possível dizer se S. jollyae é uma espécie amplamente distribuída e negligenciada em estudos anteriores na região Neotropical ou trata-se de uma espécie recém-chegada. Quaisquer que sejam as origens destas populações de S. jollyae, parece ser uma espécie bem estabelecida e adaptada a uma ampla faixa de condições nos neotrópicos.

International audience; The distribution of heavy metals in recent sediments deposited along the Tietê River, a highly polluted river in southeast region of Brazil was studied. Around the metropolitan area of São Paulo city (25 million people), the pollution is related to municipal wastes and industrial effluents with reinforced downstream by agricultural activities. The observed increase of heavy metal concentrations is particularly important for Zn in the upper basin and Cu, Co and Cr at mouth. Geo-accumulation index calculation, related to the regional background, showed that the sediments along the basin are seriously polluted by heavy metals of anthropogenic origin, mainly Cu, Co, Cr and Zn. Calculated index suggests medium to very strongly pollution.

Espera-se também fornecer subsídios para o manejo e planejamento adequado para o uso múltiplo dos recursos hídricos, permitir o reconhecimento das áreas prioritárias para o controle da poluição hídrica e propor a implantação de medidas mitigadoras dos problemas de degradação ambiental. As amostragens de água e sedimento foram realizadas na Bacia hidrográfica do Tietê, em dois pontos do rio Tietê (P1 e P2) e, em um ponto do rio Capivara (P3), no município de Botucatu - SP. Considerado importante rio, apesar de receber grandes cargas de esgoto na região metropolitana de São Paulo, o Tietê é dotado de aproveitamento múltiplo das águas e facilidade de articulação com a região oeste. O rio Tietê, na comunidade do Rio Bonito fica a 35 km de Botucatu e faz parte da bacia hidrográfica da hidrovia Tietê - Paraná. O rio Capivara nasce em Botucatu- SP e deságua no rio Tietê. É considerado um dos mais importantes afluentes da margem esquerda da bacia do rio Tietê na região de Botucatu e possui cerca de 30 km de extensão. Foram avaliadas as seguintes variáveis: atributos organolépticos (aspecto visual da água e odor); variáveis fisico-químicas (cor, turbidez, temperatura do ar e da água, pH, condutividade elétrica, oxigênio dissolvido e demanda bioquímica de oxigênio); espécies químicas (carbono orgânico total, nitrato, nitrito, fosfato total e metais potencialmente tóxicos – na água e no sedimento – Cd, Co, Cu, Ni, Mn, Pb e Zn) e; microbiológicas (coliformes totais e termotolerantes), em três pontos diferentes estrategicamente preestabelecidos (P1, P2 e P3)... The objective of this work was to monitor the water quality in water supply systems located in Tietê Watershed, around Botucatu City, Sao Paulo State, to identify areas where the water quality can be more degraded by human action. The work may supply assistance to the management and adequate planning to multiple uses of water resources, the recognition of priority areas for the hydric pollution control and propose mitigation measures for the environmental degradation. The water and sediment samplings were collected in Tietê Watershed, in two collect points in Tiete River (P1 e P2) and, one collect point in Capivara River (P3), in Botucatu City – SP. Tiete River is considered very important river and receives sewage from Sao Paulo, the Capital and surroundings. It has multiple use of its water and connects to the west region of the State. Rio Bonito Community is 35 kilometers from Botucatu and is at Tiete-Parana Watershed. Capivara River rises in Botucatu City and flows to Tiete River. It is one important left side affluent of Tiete Watershed and has 30 kilometers of extension. The following variables were analyzed: organoleptics properties (water aspect e odor); physic-chemicals (color, turbidity, air and water temperature, pH, electric condutivity, solved oxygen e demand oxygen biochemist); chemical species (organic carbon total, nitrite, nitrato, total fosfato e potentially toxic metals – in water and sediment – Cd, Co, Cu, Ni, Mn, Pb e Zn) e; micro biologics (totals and thermotolerant coliforms), in three different collect points strategically pre determinate (P1, P2 e P3). Samplings were collected quarterly, during two years (2008/2009), following a schedule according to the seasons. The criteria to choose the collect points were the Tiete River contribution related to human action rural e/or urban, also its physic conditions and easy access. Water quality analyses data were ...

International audience; Analysis of heavy metals in fluvial sediments has been used to better understand the potential hazards and critical toxicity of heavy metals mainly related to the anthropogenic influences of urban sewage, industrial effluents and agricultural activity. The present study analyzed the heavy metals, such as Cr,Cu,Ni,Zn and Pb in the bottom sediments along the Tietê river basin, a polluted watershed in the Southeast region of brazil.The distribution of the concentrations of heavy metals in the upper basin decreased in the following order: Zn>Cr>Pb>Ni>Cu, whereas, in the middle part of the basin (wich is under strong urban and industrial influences), high concentrations of Zn, Cu and Cr were abserved measuring 648,200 and 183 µg g-1 respectively. The sequential chemical extraction in relation to the total ocncentration was used to assess the potential bioavailability of heavy metals. In the upper part of the basin, the heavy metals extracted from the bottom sediments were mainly related to the residual fraction, whereas, in the middle part of the basin, the bioavailability of Zn,Cr and Ni was higher than 60%, and these metals was mainly related to the iron oxide phase.The high concentration of heavy metals observed in the middle basin of the Tietê river(after the metropolitan area of São Paulo)when compared with the average concentration found in the geochemical bottom,showed that,in terms of enrichment factor and geoaccumulation index,the degree of pollution by Zn is high and by Ni is high to moderate in the down stream direction.

This work aimed to study the anthropogenic effects on the Cintra Stream and their interrelations with soil occupation, polluting sources, water use and contributions to the water quality of two large bodies of water: the Tietê River and the Guarani Aquifer. To study the variables, variance analyses were followed by Tukey’s test, at a 5% significance level. All studied parameters indicated that the stream shows self-depuration capacity starting at site 3 due to dilution, oxygenation of the water and consequent biodegradation of the existent organic matter. Corrective measures at sites 1 and 2 followed by preventive actions in agricultural areas (S3 to S7 ) will permit use of the stream water in the rural area. Fue evaluada la calidad del agua de la cuenca del arroyo de Cintra a través de análisis en 2 periodos (junio/2005 a mayo/2006 y enero a diciembre/2007), con colectas bimestrales en 8 puntos distintos con las variables físicas y químicas pH, NO3-, NO2-, DBO 5, OD y COT. Este trabajo se propuso estudiar los efectos antropogénicos en el arroyo de Cintra y sus interrelaciones con la ocupación del suelo, fuentes contaminantes, uso del agua y contribuciones para la calidad de las aguas de dos grandes cuerpos de agua: Río “Tietê” y Acuífero “Guaraní”. Para analizar las variables, fueron realizadas análisis de varianza seguidas del Test de Tukey, con un nivel de significancia de p

International audience; The spatial variation of some trace elements (Ni, Cr, Zn, Cu, Sc, Co, Rb, Sr, Cs, Pb, Th and U) was studied in the bottom sediments of the Tietê river in São Paulo, Brazil. The main objective was to identify the enrichment factors and possible anthropic contributions to the observed high toxicity of these chemical elements in this drainage basin, which crosses the metropolitan area of São Paulo city with about 20 millions people and receives a large load of domestic and industrial wastes. The chemical analyses were performed after the chemical extraction procedure using alkaline fusion with Lithium tetraborate. An Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) and a Neutron Activation Analysis (NAA) were used for the analytical purposes. The enrichment factor was calculated by the relationship between the concentration of each trace element in the bottom sediment and the natural soil background in the drainage basin, weighted by the conservative Sc.
